Pontiac Sunfire 1998 - doesn't start engine - anti theft system locked
Hi, I'm owner of a Pontiac Sunfire 1998, Standard transmision 5 gears, without AC. I stopped the car for fifteen days to fix it of many subjects: I've changed bearings and give maintenance to the starter motor and to the generator. First I've disconnected the battery.
After this fifteen days I've reconnected the battery to take the car to a mayor motor cleaning (it spills oil). The engine doesn't start, the "volts" light (battery sign) flashes unconstantly (like if it has a bad connection) and the "theft system" led remains on (not blinking) all time.
I've realized that maybe this protection was enabled because of the battery connects and disconnects, so I've brought a fuel injection engineer to get the computer scanned and erase the error code...
...was not succesful, he found the code in the scanner and have erased it but the "theft system" led remains still on. He told me to do the following:
- open the switch;
- bump on the starter once,
- release the key but keeping the switch open.
- wait for a self recognition of the computer till the led get off before starting the car.
that was 2 days ago, I've realized this operation several times and nothing works yet, even I've waited 4 or 5 hours between operations,
After this I've disassembled all the dashboard in order to check wire status, I've found nothing. I've also checked all the motor harnesses and connections and have found one or two cables without isolation, have them isolated. I also have follow the computer harnesses and disconnect and reconnect them. Same malfunction, not more nor less.
I am urged to find a solution to this problem, please somebody help me with this problem.
I had the same thing and I had to do the bump starter and wait 10 min. and do it again.I did this for about 15 times.I was told that it depends on how far out of sink it had become.hope that it works for you.I asume that you do not have a chip in you key.

You may want to do some research on the code. The basic problem is the anti-theft system is not seeing a crank signal and shutting down the fuel pump. It could be the security system, or the crank sensor, or other issues. If you have auto start or a remote starting system it can cause these problems too.
Your vehicle is equipped with the Passlock theft-deterrent system. Passlock is a passive theft-deterrent systemT. he system is armed once the keyi s removed from the ignition. Passlock enables fuel if the ignition lock cylinderi s turned with a valid key. If a correct key is not used, fuel is disabled.
During normal operation, the THEFT SYSTEM light will go off after the engine is started. Ln the unlikely event that the engine stalls and the THEFT SYSTEM light flashes, wait until the light stopsf lashing before trying to restart the engine. Remember to release thkee y from the START position as soon as the engine starts. If after several tries the vehicle still does not start, the vehicle may need service. At this time, you may also want to check the fuses. See your Pontiac dealer for service.
If the THEFT SYSTEM light comes on while the engine is running, a problem has been detected and the system may need service. See your dealer for service. In an emergency, call the Pontiac Roadside Assistance Program at 1 -800-ROADSIDE or 1-800-762-3743.
in the 1996 sunfire GM uses an anti theft lock system. It can be triggered by all sorts of things. In order to relinquish this you must have a key to turn the ignition. These are not coded just plain cut keys. Once you attain this you put the key in and turn the ignition to the ACC position and wait ten minutes (theft lock light will turn off), turn off and take key out. You MUST do this 3 times and then the theft lock will be disarmed.
hi , not necessarily , did you replace the key and tumbler , or the ignition switch (electrical part) ? there is a password relearn procedure , attempt to start the vehicle , leave ignition on until THEFT SYSTEM indicator turns off , (approximetly 10 minutes) , turn ignition switch off , attempt to start vehicle , if vehicle starts , password has been learned ... if password does not relearn , i can post some diagnostic procedures .
